The local TCP performance is good enough that I won't care if IL goes away someday. On the other hand, there's no immediate push to get rid of it; we support IL in our new NAT code. We have an initial implementation of IPv6 in Plan 9, thanks mainly to the efforts of Lakshman Yagati. It doesn't do IPsec yet---we prefer the easier network administration of SSL/TLS, thank you---but does come with v4/v6 NAPT-PT, hence is viable to adopt even in otherwise IPv4-only networks. These decisions are all based on the personal taste of the technical people doing the work. "smoky back rooms" are not our style. Eric
